Burrito definitely loves playing with his human friends (and we love playing with him!) but I really like seeing Burrito play with other chimps. He and Foxie play pretty frequently– I would suspect that of the chimps, Foxie is his best friend. But he and Missy play sometimes too. I caught them in a rambunctiously goofy play session this morning in the greenhouse. They were so caught up in their silliness that neither of them even noticed me taking photos through the glass window in the playroom.
